I'm crazy for the Handi-H&R! I originally bought mine in 270 and have expanded my barrel/caliber collection to: 12 gauge slug, 20 gauge Ultra slug, 22 Hornet, .223, 45/70 Govt. & .50 cal muzzleloader.
I use a variety of different scopes on mine and every one is accurate and stable.
Try looking at Greybeards web page or Graybeards Outdoors for other Handi fanatics.
